Supplementary angles measure 180°. Make an equation:
Subtract 28 to leave the variable in the parentheses alone:
Add the 2 x's together:
Your new equation is:
Divide both sides by 2 to leave the variable alone
The supplement measures 76°
Answer: 3/6 and simplfied is 1/2
Answer:
<h2><u><em>
x - 15 = 2</em></u></h2>
Step-by-step explanation:
The difference of a number and fifteen is two. Write and Algebra Sentence then solve the number.
x - 15 = 2
x = 2 + 15
x = 17
-------------------------
check
17 - 15 = 2
2 = 2
<u>the answer is good</u>
To solve this we use the
equation,
<span> M1V1 = M2V2</span>
<span> where M1 is the
concentration of the stock solution, V1 is the volume of the stock solution, M2
is the concentration of the new solution and V2 is its volume.</span>
<span>
</span>
<span>M1 = .80 g H2SO4 / g solution (1018 g solution / L solution ) (1 mol / 98.08) = 8.30 M</span>
<span>
</span>
<span>8.30 (V1) = (5.0 M) (1.5 L)</span>
<span>V1 = 0.9036 L or 903.6 mL of the stock needed</span>
